SECONDARY CONTAINMENT DIFFERENTIAL PRESSURE OUTSIDE SPECIFICATION
"On March 8, 2016 at 0232 hours [EST], Secondary Containment Zone 3 (Unit 1&2 Reactor Building) differential pressure lowered to 0.16 inches water gauge when securing Unit 1 Zone 3 HVAC for planned maintenance. Required differential pressure per SR 3.6.4.1.1 could not be maintained in the intended alignment. Zone 3 ventilation was restored to the original alignment and Zone 3 differential pressure recovered to greater than 0.25 inches water gauge at 0335 hours. Zone I (Unit 1 Reactor Building) and Zone II (Unit 2 Reactor Building) ventilation remained in service and stable. Station engineering and maintenance are investigating the Zone 3 HVAC system to determine the cause.
"This event is being reported under 10 CFR 50.72(b)(3)(v)(C) and per the guidance of NUREG 1022, Rev. 3 section 3.2.7 as a loss of a Safety Function. There is no redundant Susquehanna Secondary Containment System."
The NRC Resident Inspector has been notified.

DAMAGED SIEMENS DENSITY GAUGE
The licensee reported that a Siemens C-200 Gauge, model L 640 containing a Ra-226 0.005 Ci source, was run over by a pick up truck and damaged. Damage to the gauge was limited to the electronics package and battery. The source remains properly contained and un-damaged. A survey of the area indicates no leakage and no exposures to personnel. The gauge has been placed in a secure location and will be sent back to the manufacturer for repairs.
